The story goes like this, at first I got voice distortion when I was on call. Can you imagine in the middle of conversation, you heard "robotic" voice, I was on the phone with John and I thought he was playing prank with me...hoho...after few times then I realized it's phone problem. This is how I sent in for the 1st time..
Reason given: Faulty Cable, and replace cable.
In just less then a week, when I were travelling in the train, I realized that my phone line is off, signal shown, but no phone call nor sms can be sent...verified with few phone, they are ok, only mine have problem...and there I go again for 2nd time..
Reason given: Faulty Cable, and replace cable.?? (start to feel strange, another cable replacement)
Once, I got my phone back, I went to Dhoby ghout mrt quickly to test the line..and guess what it is still the same.....I can't make any phone call!!!! Arghh........
This time I decided to do some troubleshooting myself since I'm calling myself an Engineer hahahaha....I did observed last time that whenever there was no 3G logo, I can;t make any phone call even though the signal bar shows full strength..and once 3G logo is back, I'm okay...
So with the help of technology called Google, I find out what are these 2 and 3G things, i know 3G is where you can do fancy thing like video call, so in conclusion, it turn out they are different network.
Verify with starhub (Starhub call center is another pain, never ever got connected with the operator!!!), their 3G coverage is 99% while 2G is 99.99% as per their claim.
So possible root cause: SIM card faulty or phone faulty for 2G connection.
To cut the story short, I went down to Starhub, waiting patiently for my number while watching stupid Mr Bean show. Change SIM card, and voila....problem still there..
So what's next???!!! Of course go back to Samsung and give a good scolding to their customer service!!! hahahaha.
The result?? Motherboard replaced + Hand Delivery to my footstep :P and the most important things..Problem rectified...yippie
